Fiat contemplating sub-brand to compete with Dacia, Datsun

You can add Fiat to the admittedly short list of automakers considering a low-cost brand to rival Dacia. The inexpensive Eastern European brand from Renault-Nissan has performed on the balance sheet like a premium model line, and the money the alliance is taking off the table is encouraging other players to deal themselves in. Pretty soon Nissan's Datsun sub-brand will join the Dacia party, going on sale in Russia, Indonesia and India and will claim even more rubles, rupiahs and rupees for the parent company. Volkswagen recently said it will make a decision this year on a budget line for the Chinese market. With the euthanasia of Lancia and plans to move the Fiat brand upmarket, company CEO Sergio Marchionne wonders aloud to Automotive News Europe whether there could be room for a new budget brand underneath Fiat.
We're told that the initiative has been in the idea box for five years and even moved to the stage of name considerations, like Innocenti, but worries about profit kept it from realization. If such a range were to be developed, Marchionne says it couldn't be built in Italy and stay within budget, and the company is "analyzing its manufacturing capacity outside of Europe to see if a low-cost brand is viable."

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

2015 Nissan Juke keeps its funky

The Nissan Juke is one of the most polarizing vehicles on the road today, but that doesn't mean it hasn't been a sales success, especially in Europe. Nissan is giving the the CUV its first styling refresh at the Geneva Motor Show. While the design changes will almost certainly be universal, the mechanical changes are still somewhat of a mystery for the US market. Nissan makes it clear in its press release below that it covers only the European model, and details about the North American model are coming later.
The exterior changes put a focus on making the Juke look a bit more angular and sporty. The lights on the fenders are now formed into a jagged point and somewhat echo the boomerang-shaped taillights. It also features Nissan's new, thicker V-shaped chrome grille. The door mirrors receive LED turn signals, and the lower portion of the rear receives a simulated mesh grille to look more aggressive. Other than some new color schemes, the interior is basically unchanged. However, the luggage area has been reshaped to increase storage capacity by 40 percent to 12.5 cubic feet (354 liters).
European buyers are getting a new 1.2-liter DIG-T turbocharged engine with 113 horsepower (115PS) and 140 pound-feet of torque (190Nm), and the 1.6 DIG-T also gets an increased compression ratio to produce 188 hp and is offered with either a six-speed manual or Nissan's Xtronic CVT. The all-wheel-drive system has also been upgraded with a torque vectoring system.
